The first advert that I have found for John Nicol's
business is from The Scotsman in 1859
The Scotsman 19 February 1859, page 1
DRY COLLODION PLATES
Certain and Sensitive
PURE PHOTOGRAPHIC CHEMICALS
SCOTT & ORR, CHEMISTS, 21 DUNDAS
Wholesale and Retail Agents in Edinburgh for
KEEN'S Celebrated Collodion
Nicol continued to advertise in The Scotsman, adverts appearing on 9, 12,
18, 22, 26, 30, 31 Mar + 2, 6 Apr. 1859.
Was this the same John Nicol as
gave many Wednesday lectures to
EPS and who gave an account to the British Journal of
Photography of his
Early Recollections of photography in Edinburgh?
